Question

Math. I NEED HELP. PLZ. I don't understand!

Answer 1

You plot the points and use the distance formula to find the length of the lines between the points. Distance formula: d=
`√(()x_(2)  -x_(1) )^2 + (}y_(2)  -y_(1) )^2\\`

Then use the pythagorean theorem with the sides, (C^2=A^2+B^2, c=longest side) if the equation works then it is a right triangle.
